    replaced my bulb/entire assembly about 3 weeks ago. Now TV randomly turns off, standby light blinks for 20-30 sec, then TV comes back on.

    Problem has happened 6 times over 6 hr period.

    My tv kept shutting off after about an hour. I figured some kind of overheating since it continued after replacing the bulb. There was, in the fan discharge area, a small wire which I thought could be a temperature sensing wire. I moved it out of the compartment and now the tv runs for several hours before it shuts down. Is there some type of temperature sensing device that could be failing?

You will need to replace your bulb.
It costs around $ 300.00 for a new bulb.
After you have installed it, your TV will look new once again.

This sounds like a lazy lamp--that is getting hard to start. Try a new lamp first. If you are inclined to do so--get a bard bulb and install in the old lamp housing and save some money. Get a real PHILLIPS bulb--it will last a while--compared to cheap generics that are good for maybe 6 months !!

Red flashing light


  1. Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Security light blinks when key is turned to on and will not start, also is the key supposed to be coded? 2003 saturn vue 2.2


Ok to learn the key you have to do what is call 10 minute learn , turn the key to start in attempt to start the car without turning the key off after you do this leave the key on for 10 minute until light goes out, After the security light goes out turn key off for a second or two and then try to start. If you have a new key you have to do a 30 minute learn you have to do the same thing as you did for the 10 minute learn but 3 time try and start without turning key off wait 10 minutes until security goes out then try and start again and leave key on, after you do this 3 time (30 minutes) the 3rd time is where you turn the key of for a second or two before starting.
